The Severe Storms Prediction Center in Norman, Oklahoma says another round of severe storms are possible across a large section of Iowa, this afternoon and this evening. The Primary threats include isolated, fast-moving, weak tornadoes, damaging winds, large hail, and periods of heavy rainfall.
Storms will develop this afternoon and will continue through the early evening. The greatest potential for severe weather will be during the peak heating evening commute hours from 3 pm – 7 pm. Storms should be out of our area around midnight.
Most of Iowa is under an “Enhanced Risk” for severe weather. Locations south of I-80, and east of I-35 may see a slightly great threat for severe weather. Strong to severe storms that do develop will likely be very-fast moving, moving to the N/NE at potential speeds of 50 to 60 mph.
